摘　　要：以β-紫罗兰酮为原料,先在催化剂作用下通氧气氧化,再与盐酸羟胺反应得到二肟基紫罗兰酮,在酸作用下水解为重要的医药化工中间体4-氧代-β-紫罗兰酮。With β-ionone as main starting material,first oxidized under the effect of catalyst,then reaction with hydroxylamine hydrochloride was obtained dioxime-ionone. Dioxime-ionone was hydrolized under the effect of acid was obtained 4-oxo-β-ionone, an important medical intermediate.
